The oil burner pump used is a self-priming
gear pump, which must be connected as
two-line pump via a bleed filter. There is an
intake filter and an oil pressure regulator
integrated in the pump. Pressure gauges
for pressure measurements and negative
pressure measurements must be
connected before the equipment is
commissioned.
NB: before starting the burner, check that
the return pipe is open. An eventual
obstraction could damage the pump
sealing device.
